Dogecoin Soars $40M in Value Following Chinese Exchange Opens

I don't really get the appeal of Dogecoin. I really like its intention to to keep some inflation going forever. That combined with the low transaction fees seems like it could be a currency that actually ends up being spent instead of hoarded. But, it's still 100% proof of work, so if it really does take off, a good chunk of the world's energy is going to be used to find the first n digits of SHA hashes (or whatever work Doge uses).
